“We will not be tweeting or responding to @ replies during a government shutdown,” the DOT tweeted from its handle (@USDOT).

Other administrations within the agency followed suit, with most posting the same status as the DOT.

The Pipeline and Hazardous Materials Safety Administration (@PHMSA_DOT), the National Highway Traffic Safety Administration (@NHTSAgov), the Federal Railroad Administration (@USDOTFRA) and the Federal Transit Administration (@FTA_DOT) tweeted yesterday that tweets and responses have been suspended.

The Research and Innovative Technology Administration (@RITA_DOT) tweeted, “During the government shutdown, content for this account will not be updated.”

The Federal Aviation Administration (@FAASafetyBrief) notified followers Monday that it would not update its Twitter if the government shuts down.

“Signing off! In the event of government #shutdown Tuesday, this account nor the #FAA Safety Briefing magazine email will be monitored,” the FAA tweeted.

Transportation Secretary Anthony Foxx (@SecretaryFoxx) also announced that he would not update his Twitter during the shutdown.

“I will not be tweeting or responding to @ replies during a government shutdown,” Foxx tweeted.

Administrations that are active on Facebook alerted fans yesterday to not expect updates. The Federal Highway Administration (FHWA), the FTA, the FRA and RITA each shared a status to notify fans that content will not be updated, while NHTSA changed its cover photo — the large photo at the top of the page — to present the same message.

The Office of Inspector General (OIG) noted on the homepage of its website that certain operations may be delayed or suspended.
